Dropping maintenance support for this module

Technically, I don't see any reason to continue support for this module.

Just surprising, that 69 sites are using it.

We can close this down, if nobody objects. I would then close the related issue as well.

I've marked the project to be obsolete for now. When someone will take notice and has any objections, please post them here.

Leaving the issue open for any potential discussion. Will close it in a few weeks or months when no one stops by.

But doens't the context_stack module add eca tokens to block and layout builder?

However, since ECA v1.1 there is an action plugin "Token: set context" which may achieve basically the same result:

But is that token accessible via Black or Layout condition?

No. As per module description on the project page:

This module provides a Context Stack for ECA. That enables you to access objects defined from parent and root processes.

The context stack is meant for ECA processes themselves, making tokens from parent and root processes available to a running child process.
